My invention relates to fo-otaccelerators for automobiles and moreespeci ally to accelerators for the latest type: of.Ford automobiles, an objectof this invention being to provide a foot accelerator mechanisnrwhich can be installed and operated withoutdiscontinuing throttle speedcontrol. Another object oi m invention is to prothe availabilitysand use ofthe usual hand 7 i0 vi-de an acceleratoractuated bythe foottofthe driver, which maybe operatedfrom the opposite side of thelengine to that on which thecarburetor'islocated Another object of myinvention is to pro- 715 ride-an arrangement of parts between the foot accelerator and the throttle valve so as to en-: 'able the driver to operate thesaid valvewithvout actuating'or disturbing the .hancl op'erated means for-controlling the flow of gaso- 2 line to the carburetor. i

Another obJect of my invention ispro} V vide an accelerator which will be extremely cheap, durablepsin pley and comprising a minimum number ofparts.

Another object of m invention ist '0 pro- 7 ride a tootaaccelerator or automobiles which is so constructed as to cooperate With thebralre pedalof theautomo-bile in such a main. ner as t-ozinsure that the throttle willbe closed when the brake is applied. 7

Some of the objects of my invention having been stated, other objects will appear as the description proceeds when taken in connec tion with the accompanying. drawings showi in a'preferred elnbodimentvof nyinvention,

Figure l is a side elevation of the foot pedalfor operating the accelerating means; Figure 5 is a side elevation of Figure 4. Referring more particularly to the drawings, the numeral 10 indic'atesthe engine of an automobile having the carburetor control lever 11, the rod 12, and the headbolts 18, while the numeral 14 indicates the steering column of the automobile, comprising the steering rod 15, the gasoline control rod lof,

and the spark control rod 17.. The gasoline control rod 16 has the conventional lever 18 secured thereon, and at the upper endthereof s has the hand operating lever; 19 for manually controlling the flow of gasolineto the car i I b'uretor, the carburetor :being indicated 'by 6? the numeral 20. In addition to the conven tional parts just described, I have shown the foot brake '21, the floor board 22, and the dash board 23. 7 1

V I-lavingbrieflydescribedythe conventional parts of an automobile wi'thfwhich my device f is adapted to'coo1t 'erate,I shall proceed to describe thelvarious partso f my invention. On the foot-boa'rd22 I secure the bracket "24, which isdisposed transversely ofthe automobi'le. Y Thisjbracket [24 has: a vho'le there. through for-the reception of the pivot 25 for the acceleratorpeda'l 26. ,This accelerator formajring in which is adapted tofbe se- I cured" the coiled spring 35. The other end or" the coiled springfi lo issecured in one end of the bracket 36, whiclris firmly secured to the engine by] means of one of 5 the head bolts '13 V or to the under "side of {floor board 22. Securely and rigidly mounted o onthe'igasoline control rod'16, is the lever 18,

whichfisfthe conventionallever used in the type of car shown,- and ordinarily the rod 12 is'connected to the upper end of this lever, but i 5 in my inventionIfdisconnect this rod 12 from theupper endofthe lever"18 and in place thereof I' pivotally secure at itsapex the L- I shaped lever33 andfpivotallysecure the rod 9 i 12 in the end of the shorter legof the L- shaped lever 38. a a

For the sake of clearness it might be stated 7 that theposition of parts as shown in Figure 1 in'full lines represent the foot pedal of the accelerator and the accelerator parts in the position they assume when the engine is stopped or idling, while the dotted lines show the position of parts when the foot accelerator 7 shows in dotted lines how the foot of the operthe hand control means;

is depressed to its fullest extent. Figure 2 ator will come in contact with the foot'accelerator when the foot brakes are applied. Figure 3 shows the foot accelerator closed with the hand throttle open, which makes it clear that my invention does not interferewith The method of operation of my invention is asfollows: v p 3 r VWVhen it is desired to control the flow of gasoline by the footaoceleratoiythe foot of the operator is placed on the righthandend 28 of the foota'ccelerator pedal, and this will causethe bell crank lever'to swing to the leftand push'the rod 32 to the leftagai'nst the tension of the spring 35', which in turn will 1 swing the L-shaped lever 33j on its pivot and push the rod 12' to the right,thereby opening the throttle control lever 11.: When the foot ofthe operator is released from the portion 28 of the foot pedal the coiled'spring 851 will 7 pull the foot pedal, the rod32, the L-shapedlever 83, the rodl2, and thethrottle lever 11 back into. normal position as shown by full lines in Figure 1; NVhen-tliefoot of the operator is placed on the footbrake 21, and

" case it should not be desired toy'use the'foot the brakes applied, the footof the operator will come in contact with end 27 of the foot accelerator andwill positively restore the foot accelerator means to normal position, in case the same should become stuck or the spring should become weakened ;or broken. In

accelerator means, the hand, lever19jmay be clearly shown in Figure 3.
